Abstract (en)
[origin: EP2424101A2] A power inverter system (10) includes a plurality of power semiconductor switching devices (38). Each switching device (38) includes a corresponding gate turn off resistance (40) configured to increase during starting up periods of the inverter system (10) such that the open circuit voltage of a corresponding power source (12) providing power to the power inverter system (10) does not exceed the switching device (38) blocking voltage ratings during the corresponding switching turn-off periods. The starting up period is the time required to bring the corresponding power source (12) voltage from its open circuit voltage level to a predetermined voltage which constitutes a safe operating condition for the plurality of power semiconductor switching devices (38).
